• What can cause throughput to become really slow when an ISAPI filter implements SF_NOTIFY_SEND_RAW_D

  - by Gerald

  I have an ISAPI filter for IIS6 that I've been developing for a while, but I just noticed something disturbing. Anytime I have the filter installed and I download a file, the file download becomes really slow. From a remote machine I'm getting ~120kb per second without the filter installed, and ~45kb per second with the filter installed. This seems to be related to the SF_NOTIFY_SEND_RAW_DATA callback. Whenever I register for this callback, I get the slow downloads, when I don't register for it, everything is fine. Even if I make my HttpFilterProc function just return immediately, like this: DWORD WINAPI HttpFilterProc( PHTTP_FILTER_CONTEXT pfc, DWORD notificationType, LPVOID pvNotification ) { return SF_STATUS_REQ_NEXT_NOTIFICATION; } I've also tried returning SF_STATUS_REQ_HANDLED_NOTIFICATION with the same result. Is it possible that I have some build setting on my DLL that is causing a slow execution of the callback function, or is this just the way it's going to be with ISAPI?

• How to set a Transparent Background of JPanel

  - by Imran

  Hi, I need to know if a JPanel`s bacground can be set to Transparent? My frame is has two Jpanels Image Panel and Feature Panel, Feature Panel is overlapping Image Panel, the Image Panel is working as a background and it is loading image from a remote Url, now I want to draw shaps on Feature Panel , but now Image Panel cannot be seen due to Feature Panel's background color. I need to make Feature Panel background transparent while still drawing its shapes and i want Image Panel to be visible since it is doing tiling and cache function of images. I need to seperate the image drawing and shape drawing thats why I`m using two jPanels! is there anyway the overlapping Jpanel have a transparent background? thanks

• Using TextboxList events and callbacks

  - by Wraith

  Has anyone gotten callbacks working with Guillermo Rauch's TextboxList Autocomplete? I've tried multiple ways to bind and multiple events (e.g. hover) - nothing seems to register. $('#entSearch').textboxlist({unique: true, plugins: { autocomplete: { minLength: 3, queryRemote: true, placeholder: false, remote: { url: "{{=URL(r=request, f='call/json/suggest')}}", extraParams: {type: "", guid: ""} } } }, onHover: function(token) { alert('hover 1'); } }); $('#entSearch').hover(function() { alert('hover 2'); }); $('#entSearch').bind('hover', function() { alert('hover 3'); });

• Best method for Flex to PHP communication?

  - by davr

  What is the best method for communication between Flex and PHP? In the past, we used AMFPHP with AS2, and it worked great for the most part (advantage of AMFPHP is that it also has a JSON mode that can let you seamlessly use the same remote PHP with either Javascript or Actionscript frontends). However, it seems like AMFPHP isn't realy maintained anymore. So what do people recommend to replace it? So far, what I've found is: Zend_AMF (looks too complex for us, we're not using the Zend framework otherwise) AMFPHP (there were some updated made to support Flex, and it seems fairly stable, but not sure on long-term support) XML (AS3 has nice XML handling routines, but it's more of a pain on the PHP side) WebORB (I have no experience with this) Roll-our-own using JSON or some other data-to-text serialization system (php's serialize(), XML, etc etc) Mostly I'm leaning towards AMFPHP, even because of the downsides, since that's what I'm used to. Any reason I should consider switching to something else?

• How to access the Principal from a Java service object without using FlexContext?

  - by Marplesoft

  We're building some Java objects that are exposed via BlazeDS to our flex client application. So basically the BlazeDS messagebroker servlet instantiates and invokes methods on these objects in response to client requests. Works great. We're using app server-based authentication and have set up a security constraint on the <destination> elements in the remoting-config.xml file element to prevent unauthenticated clients from being able to access these remote java objects. Again, works fine. However, there are several places within the implementation of these java objects where we want to get the currently logged on user's username. Right now we are doing this via FlexContext.getUserPrincipal(), which gives access to this but we have a nagging concern that we don't like the idea that the implementation of these objects (the service layer) has a hard dependency on a BlazeDS class. But we're not sure how else to get access to this. The same applies to accessing the ServletContext and such. Any ideas?

• How to connect to local MQseries queue using Python?

  - by Michal Niklas

  I am new to mqseries and I started with IBM WebSphere MQ curses. There are examples with MQ_APPLE and MQ_ORANGE queue managers. I have no problem with sending messages to local or remote queue with MQ Explorer, but I wanted to send such message from code: Python or Java. I tried Python pymqi library with code like this: import pymqi qmgr = pymqi.QueueManager(None) qmgr.connect('QM_APPLE') putq = pymqi.Queue(qmgr, 'Q1') putq.put('Hello from Python!') but I receive error: Traceback (most recent call last): File "mq_put.py", line 4, in <module> qmgr.connect('QM_APPLE') File "c:\Python26\lib\site-packages\pymqi.py", line 758, in connect raise MQMIError(rv[1], rv[2]) pymqi.MQMIError: MQI Error.

  i have never seen a buffer overflow exploit in live action. supporse I have found a server that seems to have vulnerabilities. Where can i get proof of the concept code preferably in c/c++ to exploit the vulnerability? eg i found this vulnerability Multiple directory traversal vulnerabilities in functions such as 'posix_access()', 'chdir()', 'ftok()' may allow a remote attacker to bypass 'safe_mode' restrictions.

• Rails 3 Form For Custom Action

  - by Andrew

  I'm having trouble routing a form to a custom action in Rails 3. Here are my routes: resources :photos do resources :comments collection do get 'update_states' end member do put 'upload' end end Here's the form_for: form_for @photo, :remote => true, :url => { :action => upload_photo_path(@photo) }, :html => { :multipart => :true, :method => 'put' } do |f| And here's the error message: No route matches {:action=>"/photos/42/upload", :controller=>"photos"} ... this is especially frustrating because "photos/:id/upload" is exactly the correct action for this form. What am I missing? EDITS - Here are the original Photo-related routes: photo_comments GET /photos/:photo_id/comments(.:format) {:action=>"index", :controller=>"comments"} POST /photos/:photo_id/comments(.:format) {:action=>"create", :controller=>"comments"} new_photo_comment GET /photos/:photo_id/comments/new(.:format) {:action=>"new", :controller=>"comments"} edit_photo_comment GET /photos/:photo_id/comments/:id/edit(.:format) {:action=>"edit", :controller=>"comments"} photo_comment GET /photos/:photo_id/comments/:id(.:format) {:action=>"show", :controller=>"comments"} PUT /photos/:photo_id/comments/:id(.:format) {:action=>"update", :controller=>"comments"} DELETE /photos/:photo_id/comments/:id(.:format) {:action=>"destroy", :controller=>"comments"} update_states_photos GET /photos/update_states(.:format) {:action=>"update_states", :controller=>"photos"} upload_photo PUT /photos/:id/upload(.:format) {:action=>"upload", :controller=>"photos"} photos GET /photos(.:format) {:action=>"index", :controller=>"photos"} POST /photos(.:format) {:action=>"create", :controller=>"photos"} new_photo GET /photos/new(.:format) {:action=>"new", :controller=>"photos"} edit_photo GET /photos/:id/edit(.:format) {:action=>"edit", :controller=>"photos"} photo GET /photos/:id(.:format) {:action=>"show", :controller=>"photos"} PUT /photos/:id(.:format) {:action=>"update", :controller=>"photos"} DELETE /photos/:id(.:format) {:action=>"destroy", :controller=>"photos"} Here are the relevant routes when I changed the route to match 'upload': photo_comments GET /photos/:photo_id/comments(.:format) {:action=>"index", :controller=>"comments"} POST /photos/:photo_id/comments(.:format) {:action=>"create", :controller=>"comments"} } new_photo_comment GET /photos/:photo_id/comments/new(.:format) {:action=>"new", :controller=>"comments"} edit_photo_comment GET /photos/:photo_id/comments/:id/edit(.:format) {:action=>"edit", :controller=>"comments"} photo_comment GET /photos/:photo_id/comments/:id(.:format) {:action=>"show", :controller=>"comments"} PUT /photos/:photo_id/comments/:id(.:format) {:action=>"update", :controller=>"comments"} DELETE /photos/:photo_id/comments/:id(.:format) {:action=>"destroy", :controller=>"comments"} update_states_photos GET /photos/update_states(.:format) {:action=>"update_states", :controller=>"photos"} upload_photo /photos/:id/upload(.:format) {:action=>"upload", :controller=>"photos"} photos GET /photos(.:format) {:action=>"index", :controller=>"photos"} POST /photos(.:format) {:action=>"create", :controller=>"photos"} new_photo GET /photos/new(.:format) {:action=>"new", :controller=>"photos"} edit_photo GET /photos/:id/edit(.:format) {:action=>"edit", :controller=>"photos"} photo GET /photos/:id(.:format) {:action=>"show", :controller=>"photos"} PUT /photos/:id(.:format) {:action=>"update", :controller=>"photos"} DELETE /photos/:id(.:format) {:action=>"destroy", :controller=>"photos"} Unfortunately 'match' didn't work any better... -- EDIT -- Just to confirm another scenario here... with this in the routes: resources :photos do resources :comments collection do get 'update_states' end member do match 'upload' end end and this in the view: form_for @photo, :remote => true, :url => { :action => 'upload' }, :html => { :multipart => :true, :id => 'photo_upload' } do |f| I still get: No route matches {:action=>"upload", :controller=>"photos"}

• ssms cannot connect to default sql server instance without specifying port number

  - by Oliver

  I have multiple SQL Server 2005 instances on a box. From SSMS on my desktop I can connect to that box's named instances with no problem. After some recent network configuration changes, when I want to connect to the default instance from SSMS on my desktop, I have to specify the port number. Before the network changes, I did not have to specify the port number of the default instance. If I remote to any other box (including the one in question), and use that box's SSMS to connect to that default instance, success. From my desktop, and only from my desktop, I have to specify the port number. Is it a SQL Server configuration that I've missed? Is it possible something in my PC's configuration is getting in the way? Where would I look, or what could I pass on to the network folks to help them resolve this? Any help is appreciated.

• Breakpoints are ignored when debugging in Visual Studio 2008 on 64-bit system

  - by Arnold Zokas

  I'm trying to debug an ASP.NET web application in this environment: Windows Server Standard 2008 SP2 x64 Single-core CPU 4GB RAM Visual Studio 2008 with Remote Debugger SP1 .NET 3.5 Web Application running in IIS in 64-bit mode The code I am trying to debug is a simple event handler with some basic sequential code. What I observe is that breakpoints get randomly ignored and VS often exits debug mode when I try to step through the code. The code is compiled in debug mode. I've tried all the usual steps: iisreset, reboot VM, rebuild solution, reinstall Visual Studio. Any ideas?

• Using PostRequestHandlerExecute, Flush and Close to clean up after a request - why is this bad?

  - by Erwin

  After some requests I need to clean up after the user - by calling a remote web service to release some resources if I guess the user doesn't need them anymore. It is ok to leave them hanging and letting them time out on the other server, but the polite thing to do is to inform it that I do not need them anymore. I do not want to waste the users time waiting for cleaning - so I tried to find place to put it. First I tried Application_EndRequest, but I needed something later. Then I found PostRequestHandlerExecute which seemed like a nice place, but I still need a Flush and Close to release the connection to the user. Protected Sub Application_PostRequestHandlerExecute(ByVal sender As Object, ByVal e As System.EventArgs) Response.Flush() Response.Close() ' Simulation of clean up activity: System.Threading.Thread.Sleep(4000) ' Really a couple of web service calls End Sub Is there some other place I could put these lengthy clean up routines?

  Hello, I have a probleme with jquery.ui.autocomplete 1.8 rc2 in IE7 or IE8 with the following CSS (inside jquery.ui.autocomplete.css) : .ui-menu { list-style:none; padding: 2px; margin: 0;display:block; height:200px; overflow:scroll; } I'm using the demo from the project called : demos\autocomplete\remote-jsonp.html It's working perfect with firefox but with IE7 or 8, each time I click on the scroll bar to see the end of the list, it selects an element instead of scrolling down. Do you please have a solution to have a fixed height with jquery.ui.autocomplete and a scroll bar working with IE ? Thank you very much

• SecurityException when accessing (ejb2-) session bean via local interface in JBoss 5

  - by sme

  I have the following problem with an EJB 2 SessionBean when deploying in JBoss 5: The SessionBean (called LVSKeepAliveDispatcher) requires a specific user role (called "LVSUser"), specified by <method-permission > <description></description> <role-name>LVSUser</role-name> <method > <description></description> <ejb-name>LVSKeepAliveDispatcher</ejb-name> <method-name>*</method-name> </method> </method-permission> in ejb-jar.xml. I now want to access this SessionBean from a Service (i.e. a class implementing the org.jboss.varia.scheduler.Schedulable interface that is then registered as a service) running inside the same JBoss instance. This is my jboss-service.xml: <server> <mbean code="org.jboss.varia.scheduler.Scheduler" name="lvs:service=TranslationService"> <attribute name="StartAtStartup">true</attribute> <attribute name="SchedulableClass">de.repower.lvs.server.service.translation.TranslationService</attribute> <attribute name="SchedulableArguments"></attribute> <attribute name="SchedulableArgumentTypes"></attribute> <attribute name="InitialStartDate">NOW</attribute> <attribute name="SchedulePeriod">60000</attribute> <attribute name="InitialRepetitions">1</attribute> <attribute name="TimerName">jboss:service=Timer,name=TranslationServiceTimer</attribute> <depends><mbean code="javax.management.timer.Timer" name="jboss:service=Timer,name=TranslationServiceTimer"/></depends> <depends>jboss.j2ee:service=EJB,jndiName=de/repower/lvs/i18n/sessionbeans/LVSTranslation</depends> </mbean> As the service is deployed in the same vm as the session bean I want to call the session bean via the local interface, but I get a SecurityException when I try to create an instance. When instead I do a lookup of the RemoteInterface it works. This is the code inside the perform method of my service class: public void perform(Date now, long remainingRepetitions) { try { final UsernamePasswordHandler handler = new UsernamePasswordHandler(USERNAME, PASSWORD); final LoginContext lc = new LoginContext("client-login", handler); lc.login(); // Trying to instantiate an LVSKeepAliveDispatcher via remote interface // This part works LVSKeepAliveDispatcher localvHome = LVSKeepAliveDispatcherUtil.getHome().create(); LOGGER.info("Successfully instantiated an LVSKeepAliveDispatcher " + localvHome.toString()); // Trying to instantiate an LVSKeepAliveDispatcherLocal via local interface LVSKeepAliveDispatcherLocal localvLocalHome = LVSKeepAliveDispatcherUtil.getLocalHome().create(); // this code is unforunately never reached LOGGER.info("Successfully instantiated an LVSKeepAliveDispatcherLocal " + localvLocalHome.toString()); lc.logout(); } catch (final Exception ex) { LOGGER.error("Error: ", ex); } } Exception: 2009-02-17 10:38:02,266 INFO [lvsi18n] (Timer-2) Successfully instantiated an LVSKeepAliveDispatcher de/repower/lvs/server/service/alive/sessionbeans/LVSKeepAliveDispatcher:Stateless 2009-02-17 10:38:02,297 ERROR [org.jboss.ejb.plugins.SecurityInterceptor] (Timer-2) Error in Security Interceptor java.lang.SecurityException: Authentication exception, principal=internalSystemUser at org.jboss.ejb.plugins.SecurityInterceptor.checkSecurityContext(SecurityInterceptor.java:321) at org.jboss.ejb.plugins.SecurityInterceptor.process(SecurityInterceptor.java:243) at org.jboss.ejb.plugins.SecurityInterceptor.invokeHome(SecurityInterceptor.java:205) at org.jboss.ejb.plugins.security.PreSecurityInterceptor.process(PreSecurityInterceptor.java:136) at org.jboss.ejb.plugins.security.PreSecurityInterceptor.invokeHome(PreSecurityInterceptor.java:88) at org.jboss.ejb.plugins.LogInterceptor.invokeHome(LogInterceptor.java:132) at org.jboss.ejb.plugins.ProxyFactoryFinderInterceptor.invokeHome(ProxyFactoryFinderInterceptor.java:107) at org.jboss.ejb.SessionContainer.internalInvokeHome(SessionContainer.java:639) at org.jboss.ejb.Container.invoke(Container.java:1046) at org.jboss.ejb.plugins.local.BaseLocalProxyFactory.invokeHome(BaseLocalProxyFactory.java:362) at org.jboss.ejb.plugins.local.LocalHomeProxy.invoke(LocalHomeProxy.java:133) at $Proxy193.create(Unknown Source) at de.repower.lvs.server.service.translation.TranslationService.perform(TranslationService.java:68) at org.jboss.varia.scheduler.Scheduler$PojoScheduler.invoke(Scheduler.java:1267) at org.jboss.varia.scheduler.Scheduler$BaseListener.handleNotification(Scheduler.java:1235) at sun.reflect.GeneratedMethodAccessor281.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.jboss.mx.notification.NotificationListenerProxy.invoke(NotificationListenerProxy.java:153) at $Proxy87.handleNotification(Unknown Source) at javax.management.NotificationBroadcasterSupport.handleNotification(NotificationBroadcasterSupport.java:257) at javax.management.NotificationBroadcasterSupport$SendNotifJob.run(NotificationBroadcasterSupport.java:322) at javax.management.NotificationBroadcasterSupport$1.execute(NotificationBroadcasterSupport.java:307) at javax.management.NotificationBroadcasterSupport.sendNotification(NotificationBroadcasterSupport.java:229) at javax.management.timer.Timer.sendNotification(Timer.java:1234) at javax.management.timer.Timer.notifyAlarmClock(Timer.java:1203) at javax.management.timer.TimerAlarmClock.run(Timer.java:1286) at java.util.TimerThread.mainLoop(Timer.java:512) at java.util.TimerThread.run(Timer.java:462) To further diagnose the error I debugged through the SecurityInterceptor and found that in the first case (successful creating an instance via the remote interface) the security context "lvs-security" (which I defined in login-config.xml) is being used whereas in the second case (failure when creating an instance via the local interface) the generic security context "CLIENT-LOGIN" is being used. This is the definition of the securit context "lvs-security" in login-config.xml: <application-policy name = "lvs-security"> <authentication> <login-module code = "org.jboss.security.ClientLoginModule" flag = "required"> </login-module> <login-module code = "de.repower.lvs.security.UsersRolesLoginModule" flag = "sufficient"> </login-module> <login-module code = "de.repower.lvs.security.login.LVSLoginModule" flag = "required"> <module-option name = "lvs-jboss-host">localhost</module-option> <module-option name = "lvs-jboss-jndi-port">1099</module-option> </login-module> </authentication> </application-policy> I'm now kind of stuck and hope someone can give me a hint about where to further look for the cause of the problem. This worked fine in JBoss 3.2.7. Edit: My current workaround for this problem: create a new container configuration in jboss.xml and remove the security interceptor stuff from this configuration use this newly created container configuration for all my session beans that I only use locally (i.e. via local interface).

• Global "ajax call" notification with asp.net mvc/jquery

  - by Joel Martinez

  I need to be notified any time a largeish asp.net mvc web application makes an ajax call to the server. We're using both jquery, and the built-in Ajax.* methods to do the remote calls, and I would like a global way of knowing when we make a call without having to manually inject some sort of "IsMakingCall" method to every request. The root problem we're trying to solve is session timeout. If the user leaves a page up and goes to lunch (for example), they get errors when they get back because the ajax call is returning the login page instead of the expected json or partial html result. My idea was to have a js timer which would be reset any time we make an ajax call. That way, if the timer runs out (ie. their session has now timed out) I can just auto-log them out. This is how sites like bank of america and mint.com work. Thanks!

• How to get roles with JSR 196 authentification in GlassFish?

  - by deamon

  I want to use a custom authentication module conforming to JSR 196 in GlassFish 3. The interface javax.security.auth.message.ServerAuth has the method: AuthStatus validateRequest( MessageInfo messageInfo, javax.security.auth.Subject clientSubject, javax.security.auth.Subject serviceSubject ) AuthStatus can be one of several constants like FAILURE or SUCCESS. The question is: How can I get the roles from a "role datebase" with JSR 196? Example: The server receives a request with a SSO token (CAS token for example), checks whether the token is valid, populates the remote user object with roles fetches from a database via JDBC or from REST service via http. Is the role fetching in the scope of JSR 196? How could that be implemented? Do I have to use JSR 196 together with JSR 115 to use custom authentication and a custom role source?

• jQuery.load() Retrieving partial page content causes duplicate ID in DOM

  - by Warren Buckley

  Hello all, I currently have a JS function that allows me to load partial content from another page into the current page using jQuery.load() However I noticed when using this that I get a duplicate ID in the DOM (when inspecting with FireBug) This function is used in conjuction with a Flash Building viewe so it does not contain any code to retrieve the URL from the anchor tag. function displayApartment(apartmentID) { $("#apartmentInfo").load(siteURL + apartmentID + ".aspx #apartmentInfo", function () { //re-do links loaded in $("a.gallery").colorbox({ opacity: "0.5" }); }); } The code above works just fine in retrieving the content, however it just bugs me that when inspecting with firebug I get something like this. <div id="apartmentInfo"> <div id="apartmentInfo"> <!-- Remote HTML here..... --> </div> </div> Can anyone please suggest anything on how to remove the duplicate div?

• AsyncTask, RejectedExecutionException and Task Limit

  - by Samuh

  I am fetching lots of thumbnails from a remote server and displaying them in a grid view, using AsyncTask. The problem is, my grid view displays 20 thumbnails at a time, so that creates 20 AsyncTasks and starts 20 executes, one per thumbnail. I get RejectedExecution exception in my code. I recall reading somewhere that there is a limit to number of tasks that AsyncTask can have in its queue at a time, i might be hitting that. Was this bar lifted? Is there a way to increase this limit? Is it safe to just ignore this exception?(by having an empty catch(RejectedException e){} block?) I am running this code on Android 1.6 emulator and the API level in my code(minSDKVersion is 3). [EDIT: Added SDK and API level info]

• Run a shell command with arguments from powershell script

  Hello, I need to extract and save a some tables from a remote SQL database using bcp. I would like to write a powershell script to invoke bcp for each table and save the data. So far I have this script that creates the necessary args for bcp. However I can not figure out how to pass the args to bcp. Every time I run the script it just shows the bcp help instead.

• What useful GDB scripts have you used/written?

  - by nik

  People use gdb on and off for debugging, of course there are lots of other debugging tools across the varied OSes, with and without GUI and, maybe other fancy IDE features. I would like to know what useful gdb scripts you have written and liked. While, I do not mean a dump of commands in a something.gdb file that you source to pull out a bunch of data, if that made your day, go ahead and talk about it. Lets think conditional processing, control loops and functions written for more elegant and refined programming to debug and, maybe even for whitebox testing Things get interesting when you start debugging remote systems (say, over a serial/ethernet interface) And, what if the target is a multi-processor (and, multithreaded) system Let me put a simple case as an example... Say, A script that traversed serially over entries to locate a bad entry in a large hash-table that is implemented on an embedded platform. That helped me debug a broken hash-table once.

  I have the following problem deploying my application. It uses JMS and a remote openMQ for communication between servers. The problem is that the connection is not fully reliable so it can be up or down. For reconnecting I set the jms reconnect glassfish property so it reconnects if at some moment the connection gets lost. The problem arises when i try to deploy the application and there is no connection. It looks like it keeps retrying the connection but the application does not finish deployment until connection is available. Is it possible to configure it in any way that the deployment continues even if there is no connection and keeps retrying until there is connection available? Thanks a lot.
